创新投资对经济高质量发展的影响研究——基于产业结构升级的中介视角

创新投资是否以及如何影响经济高质量发展是近年来大家关注的焦点.从理论上阐述创新投资如何通过产业结构升级来影响经济高质量发展,并以中国2008—2017年30个省、市以及自治区的数据作为样本,借助中介效应模型,实证检验上述影响机理和效应.研究发现:创新投资能够促进经济高质量发展;创新投资与产业结构升级显著正相关;产业结构升级在创新投资与经济高质量发展之间具有完全中介作用,即创新投资是通过影响产业结构升级来影响经济高质量发展的;不同地区的创新投资对经济发展高质量的影响程度不同,其中,西部地区的创新投资对经济高质量发展的影响强度较大,而且产业结构升级的中介效应也更为明显.

Research on the Influence of Innovation Investment on High-quality Economic Development: Based on the perspective of industrial structure upgrading Intermediary

Whether and how innovation investment affects high-quality economic development has been the focus of attention in recent years.Theoretically expounds how innovation investment influences high-quality economic development through industrial structure upgrading, and empirically tests the above influence mechanism and effect by means of the mediating effect model with the data of 30 provinces, municipalities and autonomous regions from 2008 to 2017 as samples.The results show that innovation investment can promote high-quality economic development.Innovation investment is significantly positively correlated with industrial structure upgrading.Industrial structure upgrading plays a completely intermediary role between innovation investment and high-quality economic development, that is, innovation investment influences high-quality economic development by influencing industrial structure upgrading.The influence of innovation investment in different regions on the quality of economic development is different, among which, the influence of innovation investment in western regions is stronger, and the intermediary effect of industrial structure upgrading is more obvious.
